Better check the SS website, depending on your year of birth, it may be different. For me, 66 year + 2 months is considered full retirement age................
One thing to do regardless is to retire debt-free. Without debt (and hopefully with a nice retirement account and/or pension) I hope to live on the SS, roll over my IRA/401k's (slowly to minimize taxes) to Roth's, and (Lord willing) leave a nice inheritance to the kids/grandkids (Thank you Dave Ramsey!).
That or spend it all on riotous living and die penniless...
